ABSTRACT:
Resolution of DL-S-benzoyl-.beta.-mercaptoisobutyric acid into its optical antipodes is effected by treating the DL-acid in solution with D-(+)-N-benzyl-.alpha.-phenethylamine. The D(-)-S-benzoyl-.beta.-mercaptoisobutyric acid itself as well as its salts, esters or derivatives can be obtained advantageously by this process.
